LM3421
Product Details Description: The LM3421 and LM3423 family of devices are versatile high voltage N-channel MOSFET controllers for LED drivers. They can be easily configured for buck, boost, buck-boost and SEPIC topologies. This flexibility, along with a rated input voltage of 75 V, makes these controllers ideal for illuminating LEDs in a large family of applications. An adjustable high-side current-sense voltage allows tight regulation of the LED current with the highest possible efficiency. The LM3421 and LM3423 devices use Predictive Off-Time (PRO) control, which is a peak current mode control...
